### Purpose
<!-- Linking this pull request to the issue -->
Linked issue: close #2473
<!-- What is the purpose of the change -->
### Brief change log
This PR fixes the flaky test `FlussAuthorizationITCase.testRebalance`.
The error happens because of a race condition between creating a table and
the rebalance operation. Sometimes, `RebalanceManager` tries to build a cluster
model while a table is still being created. In this specific moment, the table
has a Leader elected, but the replica list is not updated yet. This caused the
error `RebalanceFailureException: Leader replica is not in the bucket`.
### Tests
- Added `testRebalanceDuringConcurrentTableCreation` in
`FlussAuthorizationITCase`.
- I ran the new test locally more than 50 times and it passed. Before the
fix, it failed consistently.
- I also ran the full Maven build locally and all tests passed.
### API and Format
no
### Documentation
